or Niiw YORK, N. Y.

MANUFACTURING SEAT/[LESS FELT GOODS.

Specification of Letters Patent No. 12,843, dated February 6, 1855.

To all whom t may concern Be it known that I, JOHN H. BLOODGOOD, of the city of New York, in the county and State of New York, have invented a new and useful Improvement in the Manufacture of Seamless Articles of Felt, of which the following is a full and exact description.

My improvement consists in the method of forming the various parts necessary to the production of seamless garments or other articles of felt, as follows: A batvof wool, fur or other felting material is formed in every respect as for making ordinary felt cloth, being in a flat sheet of any desired width or length and having the fibers crossed by any of the usual methods. This bat is placed upon the machine usually* known as the hardener, felter or jigger, between two linen or cotton sheets. Above or below these sheets is placed a pattern (either permanently attached to, and forming a part of the machine, or movable), which pattern is of considerable thickness, say half an inch or upward, and made to conform in shape to the article required or any portion thereof; reducing or removing so much of the pattern as may be deemed necessary where a union corresponding to a seam, is subsequently to be effected; so that in those places a margin, say of two or three inches may be left, which margin, together with all other part-s of the bat not directly embraced vwithin vthe limits of the pattern, being protected from the action of the hardener or felter in consequence of the interposition of the pattern will remain nearly or quite unfelted and soft, whereas those parts which are covered by, or rest upon the pattern will receive the whole weight and action of the hardening plate and will consequently become thoroughlyl felted or hardened. This being accomplished, the bat is taken from the machine and all the soft unfelted parts removed except such as it may be necessary to retain in order to effect a union when required to produce the proper form for the article desired. Having thus prepared the bat, and having, by this process obtained margins of soft unfelted. wool,

cles are of cou-rse to be finally subjected to the fulling process as usual.

The annexed drawings forming part of this specification represent in Figure 1 by the red lines A A A the outlines of the bat; by the black lines B B the form of the pattern for a coat body-the dotted lines, showing the margins that are to be left; in Fig. 2, the red lines C C indicate the outlines of the bat-the blackI lines D D the form of a pattern for a sleeve, and the dotted lines, the

margins to be left to produce the cylindrical or conical form and also for uniting to the body.

In the specimens or samples sent that marked B is the body of a coat, having one half united and the arm attached-the other half being left to show the effect of the pattern and the soft margins (which are less perfect than when made on a larger scale). That marked S' is the sleeve piece.

.Having thus fully described my invention and its application, what I claim there- `85 The method of forming the various parts necessary to the production of seamless articles of felt, by the use of a movable or stationary pattern in the manner and for the purposes above described, but I do not claim the manner of forming the bat or of uniting the several parts as both are old and well known processes.
